you cannot fix a broken sensor the only thing you can do is replace it I'm guessing you live in a emission tested state
On a Ford F-250 4.6 V8 engine : Bank 1 is the passenger side of the engine Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
The diesel has two. Sensor one is closer to the engine.
16518- P0134 O2 Sensor Circ.,Bank1-Sensor1 No Activity Detected 16519- P0135 O2 Sensor Heater Circ.,Bank1-Sensor1 Malfunction
O2 Sensor Stuck Lean (Bank1 Sensor1).
Bank 1 is the passenger side of your V6 in a Ford Ranger Sensor 1 is somewhere close to the engine before the exhaust enters the catalytic converter
On a 1995 Mercury Cougar ( V8 and V6 ) Bank 1 is the passenger side of the engine Sensor 1 would be close to the engine before the exhaust passes through the catalytic converter

On a Ford F-150 ( V8 and V6 engines ) Bank 2 is the drivers side of the engine Sensor 1 is close to the engine before the exhaust enters the catalytic converter
Oxygen sensor circuit slow response (Bank2, Sensor1). You have a fuel system problem or a bad computer or sensor.
Passenger side is bank 2. Sensor 1 is in front of the Cat., and sensor 2 is in back of the Cat.
They are located on the passenger side. Sensor1 is right past the exhaust manifold, and sensor 2 is after the cat.
